Embodiment Construction

[0023] In the following, the technical means adopted by the present invention to achieve the intended purpose of the invention will be further described in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0024] The river bed of the present invention is the surface of the river bottom in contact with the river water. The river bottom elevation is the drop of the river terrain. The river bottom elevation of the present invention refers to the depth of the pits or gravel pits in the river. The bottom elevation may be a variable within a certain range. The pit depth in the present invention refers to the average depth, and the river bottom elevation refers to the average river bottom elevation. The river bed plane in the present invention refers to the plane formed by the top edge of the pit, such as figure 2 shown.

[0025] In a specific example of the present invention, as figure 1 , 2 As shown, the river purification system o...

Abstract

The invention relates to a river purifying system. The river bed of the river comprises a pit with depth of greater than or equal to 3m; and a convex falling sill is arranged in the pit. Due to the falling sill design, the water level is lifted by use of the falling sill, the upstream water flow velocity of the falling sill is reduced, and the settling volume of pollutants is increased; and meanwhile, when the water flow passes through the falling sill, the contact area between the water flow and air is increased, thus the aeration quantity is increased, and water purification is realized. Moreover, due to the unique wetland structure, the non-point source pollution can be effectively intercepted. After the treatment of the river purifying system provided by the invention, the water quality can be improved to the level IV.

Description

technical field [0001] The invention relates to a river purification system, in particular to a ditch-pond series system of arid and water-deficient rivers. By increasing the hydraulic retention time and reducing the pollutant load in the water flow, the water-deficient river becomes a green ecological corridor, belonging to Water conservancy engineering technology field. Background technique [0002] With the rapid development of my country's social economy, on the one hand, the ineffective control of river pollution has led to increasing river pollution loads; Deterioration continues, the ecosystem continues to decline. The increasing degradation of river ecosystems has restricted the further development of social economy. Therefore, rebuilding and repairing the damaged river system, coordinating the water conservancy and ecological functions of the river, and restoring the purification capacity are urgent needs for the current economic and social development and ecologic...
